In addition, if the catheter is retained for a long time, if you do not pay attention to exercise bladder function, it will also cause bladder atrophy and loss of bladder function. The third aspect of long-term indwelling catheter will cause bladder stones, because the catheter is a foreign body in the bladder after all, after a long time of indwelling, the crystals in the urine gradually precipitate and adhere to the catheter, thus forming stones.
